Constructivism and instructional design: more considerations

In this series of blog posts, I am considering the implications of learning and development for knowledge workers in the modern workplace, the limitations of the Systems Approach to training, and how to implement a Constructivist learning environment that can effectively and efficiently support knowledge workers.

Now read on...

In yesterday's post, and based on the work of Michael Molena, I suggested that the epitome of the Systems Approach, ADDIE, was less a development process and more a set of heuristics to facilitate instructional designers' efforts to develop e-learning content. I also outlined M. David Merrill's work to identify fundamental invariant principles of "good" instructional design, regardless of pedagogy. Merrill asserts that there is a core of consistent "Principles of Instruction" that we may use as the basis for content development regardless of the actual methodology used.

Merrill's primary and central principle of instruction is task-centered learning. A task is an activity that represents a problem that may be encountered in a real-world situation. Learning objectives or samples of the types of problems learners will be able to solve at the end of the learning sequence may also substitute for a task. A progression through problems of increasing difficulty are used to scaffold the learning process into manageable tiers of difficulty. The courseware should relate to real world problems.

Learner guidance helps focus the learner’s attention on critical elements of the information and relate these critical elements to the portrayal. The learner guidance that enhances the demonstration is indicated by bullets.

(2006a, p.4)

Merrill recognizes three categories of classification that provide information and can be portrayed:

  1. Kinds-of
  2. How-to
  3. What-happens

Kinds-of category

Concept classification occurs when learners must discriminate among members of two or more related categories of objects or events. An effective presentation/demonstration for concept classification (kinds-of) requires the following instructional activities.

  1. Tell learners the name of each category or alternative procedure.
  2. Show learners an example of each category.
  3. Provide learners a definition for each category.
  4. Show learners examples of each category.

How-to category
Procedure learning occurs when learners must carry out a series of steps. A presentation/demonstration for a procedure (how-to) involves the following instructional
activities:

  1. Show learners a specific instance of the whole task.
  2. Demonstrate each of the steps required to complete the whole task.
  3. Show the consequence of each step.
  4. Summarize the steps in the procedure and their sequence.

What-happens category
Process learning occurs when learners understand how some device works or the process underlying some phenomenon. A presentation/demonstration for a process (what-happens) involves the following instructional activities.

  1. Demonstrate the process in a specific, real or simulated situation.
  2. Repeat the demonstration for several increasingly complex scenarios.

In tomorrow's post we shall examine principles for the effective use of media in this learning environment.

Is Constructivism incompatible with Instructional Design?

Before looking in depth at Constructivist Learning Environments (CLEs), we need to investigate the question "Is Constructivism incompatible with Instructional Design?"

In his 2006 essay First Principles of Instruction, M. David Merrill reviewed a representative range of instructional design theories, models, and research, "from basic descriptive laws about learning to broad curriculum programs that concentrate on what is taught rather than on how to teach" (2006b, p.1). Based on his research, the author elicited and synthesized elements common to Instruction, and used these to assess the underlying principles of instruction. The author describes principles as "relationship[s] that [are] always true under appropriate conditions regardless of program or practice" (2006a, p.1).

To be considered by Merrill, the principles he studied had to be
  • Included in most of the instructional design theories reviewed
  • Promote more effective, efficient, or engaging learning
  • Supported by research
  • General so that it applied to any delivery system or any instructional architecture (Clark 2003)
  • Design-oriented

From this set of criteria, the author identified five principles of instruction.
  1. The demonstration principle: Learning is promoted when learners observe a demonstration.
  2. The application principle: Learning is promoted when learners apply the new knowledge.
  3. The task-centered principle: Learning is promoted when learners engage in a task centered instructional strategy.
  4. The activation principle: Learning is promoted when learners activate relevant prior knowledge or experience.
  5. The integration principle: Learning is promoted when learners integrate their new knowledge into their everyday world.

1. The Demonstration Principle

Merrill asserts that principles are most appropriate for generalizable skills. These are skills that can be applied to two or more different specific situations. He asserts that the demonstration principle is most appropriate for three types of generalizable skill:
  1. concept classification (kinds-of)
  2. carrying out a procedure (how-to)
  3. predicting consequences or finding faulted conditions in the execution of a process (what-happens).
A generalizable skill is represented by both information and portrayal. Information is general, inclusive, and applicable to many specific situations. Portrayal is specific, limited, and applicable to one case or a single situation. Information can be presented (tell) and recalled (ask). A portrayal can be demonstrated (show) and submitted to application (do).
(p.3)

The demonstration principle emphasizes the use of specific cases (portrayal). Merrill considers that lack of sufficient demonstration is a "common problem" (p.3) in much instruction. While the demonstration principle is strongly biased towards portrayal, effective and efficient instruction involves both presentation of information and demonstration with portrayal. Table 1 shows information and portrayal modalities that are consistent for each of the three categories of generalizable skill. A presentation and demonstration must be consistent if they are to support effective, efficient and engaging learning.

ADDIE, and the Systems Approach: a Critical Analysis

In yesterday's post I looked at a systems approach to instructional design and development, and suggested that this approach was an emergent property of the process whereby instructor-led courseware developers in the 1990's attempted to apply previously-effective training development techniques to the new domain of e-learning.

As an example, I looked at the ADDIE design appraoch and suggested that it could be characterized as a set of heuristics (or conceptual framework) to enable learning professionals to output content commensurate with the systems approach.


Now read on...

In this context, we can say that ADDIE will only deliver results consistent with the expertise of the content designer, as it relies on their (the designers') skills and experience in transferring information and knowledge to "deliver" learning to the recipient. In E-Learning Strategies: how to get implementation and delivery right first time, Don Morrison remarks that

...like many ISD models it fails to give clear guidance about what makes good learning content. You can follow ADDIE to the letter and still deliver mediocre content.

(2004, p.255)

It can be said that ADDIE (and similar systems' approaches to learning content development) are closer in philosophy and practice to a project management methodology than a pedagogy. In this respect they can be a useful approach when developing "one-shot" training content in environments where repetitive worker activities are the norm.

Take this scenario as an example:

  1. Production workers have just started using the new WidgetMaker 300-0 tool: it can create 3o widgets per hour.
  2. As it's operating principles are very similar to the the older WM 299-8 (20 widgets per hour) model, the organization decides that workers only need a 2-day familiarization course before beginning production with the new tool.
  3. A new production target (30 WPH) is set for workers to reflect the increased efficiency of the tool.
  4. After three months, production is still 5WPH short of target. It turns out that workers are using the old production process on the new machine, and with the expectation of attaining 30WPH are actually working harder than ever, but are still 50% short of the difference between the new and old hourly production rate. Much disgruntlement all round.
  5. It seems that there's an extra gadget on the handle of the WM300-0 that nobody noticed because of the cursory nature of the 2-day familiarization course.
  6. Time for some training...

Table 1 Systems Approach Methodology applied to learning intervention

Time

Implement

Evaluate

Outputs

Workers' productivity increased

Delta training integrated into updated operators' training program

As this example illustrates, treating learning like a project leads to "training outcomes" equivalent to project deliverables. While these training deliverables may have value in and of themselves, they have limited value for workers in the longer term. We could even say that the outputs are valid; workers have increased productivity and the next training course will have extra content to address the issue of lack of competency on the WidgetMaker 300-0. The efficiency of the system has been improved, and future trainees on the WidgetMaker 300-0 will not experience the productivity "hit" experienced by their colleagues. From a project perspective, it makes sense to fold the delta training into the course for the tool.

  • There are a number of negative consequence associated this approach
  • The delta training no longer exists as a discrete knowledge asset for the organization
  • Over time, specific knowledge of that particular learning intervention will be lost, half hidden among the overall learning goals of the WidgetMaker 300-0. Useless in effect, should another learner require remediation on that particular aspect of the tool
  • Without this discrete knowledge resource at workers' disposal, the only way to remediate their specific deficiencies on the tool is to require them to re-take the complete How to use the WidgetMaker 300-0 course. Again.

Our field of educational communications is founded on the premise that communicating content to students will result in learning. In educational communications, information or intelligence (in many different forms) is encoded visually or verbally in the symbols systems employed by each technology. During the "instructional" process, learners perceive the messages encoded in the medium and sometimes "interact" with the technology. Interaction is normally operationalized in terms of student input to the technology, which triggers some form of answer judging and response from the technology in the form of some previously encoded (canned) message. Technologies as conveyors of information have been used for centuries to "teach" students by presenting prescribed information to them which they are obligated to "learn."

(Jonassen, 2001)

Rather, Jonassen argues technology (and in particular so-called Read/Write Web technology) should enable learners to develop their skills in a constructivist learning environment (or CLE).

As a quick reminder, here's the Cliff Notes version of Constructivism:

  • We construct our own understanding of the world we live in
  • Knowledge not received from outside, but by fitting new information together with what we already know we construct knowledge in our head
  • Learning is the process of adjusting our mental models to accommodate new experiences
  • Constructivist theorists support that people learn best when they actively construct their own understanding

With this in mind (no pun intended. Well... maybe), we'll be looking at CLEs tomorrow.

E-learning ecosystems and the failure of ADDIE

Onwards with our investigation of the e-learning ecosystem and learning & development in organizations. Today's post looks at the similarly-sounding but fundamentally different Systems Approach to instructional design and learning, and why the doubtful provenance of ADDIE combined with a misunderstanding of the role of content delivery channels have failed a generation of e-learners.

Now read on...

I have suggested that a growing number of researchers and learning professionals (Dillon & Hallett, Jonassen, Rosenberg etc) are recognizing the negative affect of what Brown, Collins, & Duguid (1989) call the "breach between learning and use" (p.1) of training interventions in organizations. We have seen that both instructor-led and 'traditional' self-paced learning courseware are relatively limited in their application, and are most effective in a restricted range of circumstances. Brown, Collins, & Duguid elaborate:
Many teaching practices implicitly assume that conceptual knowledge can be abstracted from the situations in which it is learned and used. [The authors] argue that this assumption inevitably limits the effectiveness of such practices. Drawing on recent research into cognition as it is manifest in everyday activity, the authors argue that knowledge is situated, being in part a product of the activity, context, and culture in which it is developed and used.
(p.1)

To meet these conditions, we can say that it is appropriate to adapt both pedagogical approaches and the technology resources now available to enhance learners performance.

Marc J. Rosenberg concurs:

Although e-learning began as a new way to deliver training, it cannot remain that way because it is no longer able to adequately support all the learning needs of individuals and organizations by itself - if it every was. E-learning has moved in a new, somewhat unanticipated direction that is not always reminiscent of an instructional framework. To be more influential, e-learning must be reinvented. While continuing to provide a viable instructional option in a formal learning setting, it must also move toward informational and collaborative solutions that focus more prominently on the specific jobs people do. It must move beyond courseware and classrooms and into work. To reinvent e-learning is, in many ways, to reinvent learning itself.
In essence, this means transforming workplace learning, so that learning activities and resources are situated around the learner, their work environment, and their tasks, enabling learners to construct their own knowledge in the context of what resources they need to carry out their work effectively. As David Jonassen says:
In constructivist learning environments, technologies are used to situate learning tasks in a variety of contexts. With video, very rich and engaging contexts can be created.
He asserts that in the traditional organizational approach that

[u]nfortunately, most e-learning replicates the worst features of face-to-face instruction. So, it may be cheaper to "deliver" knowledge over the Internet, but it will not be more effective.

This is commonly known as the systems-based approach to instructional design & development (ISD). A system is a set of elements or components that must integrate to perform a specific function. Every job in an organization is used by the organizational ecosystem to produce a product or output. The product or output is the means by which a organization generates its assets and remains self-supporting.

There are four inputs necessary in every system to produce a product or output:

  • People: The workers making up a group and linked by a common activity.
  • Material: The raw products which go into the system.
  • Technology: The technique for achieving a practical purpose or goal.
  • Time: The measured period during which an action or process begins and ends.
In learning and development, this systems-based approach is epitomized by the ADDIE conceptual framework (see Figure 1), most notably refined by Dick & Carey in The Systematic Design of Instruction (1996).


Figure 1. The ADDIE ISD Heuristic

The ADDIE approach has been one of the core tenets of instructional design for the best part of two decades, but curiously, it may not exist! In his article In Search of the Elusive ADDIE Model (2003), Michael Molenda undertook a Livingstonian attempt to discover the source for the original reference to the ADDIE model. Molenda’s research uncovered no original reference for the ADDIE model. This lack of an original reference led Molenda to write,

I am satisfied at this point to conclude that the ADDIE Model is merely a colloquial term used to describe a systematic approach to instructional development, virtually synonymous with instructional systems development (ISD). The label seems not to have a single author, but rather to have evolved informally through oral tradition. There is no original, fully elaborated model, just an umbrella term that refers to a family of models that share a common underlying structure.
(p.1)

Hence my suggestion above that ADDIE is more properly labeled a conceptual framework; I would go so far as to say that it could even more accurately be described as a set of heuristics or "rules of thumb" to enable instructional designers from a instructor-led tradition to develop learning content by adhering to the precepts of the systems approach (see Table 1).

Table 1 The ADDIE Model

Phase

Activity

Analysis

During analysis, the designer identifies the learning problem, the goals and objectives, the audience’s needs, existing knowledge, and any other relevant characteristics.

Analysis also considers the learning environment, any constraints, the delivery options, and the timeline for the project.

Design

A systematic process of specifying learning objectives.

Detailed storyboards and prototypes are often made, and the look and feel, graphic design, user-interface and content is determined at the Design stage.

Development

The actual creation (production) of the content and learning materials based on specifications instantiated during the Design phase.

Implementation

During implementation, the plan is put into action and a procedure for training the learner and teacher is developed.

Materials are delivered or distributed to the student group. After delivery, the effectiveness of the training materials is evaluated.

Evaluation

This phase consists of (1) formative and (2) summative evaluation.

1. Formative evaluation is present in each stage of the ADDIE process.

2. Summative evaluation consists of tests designed for criterion-related referenced items and providing opportunities for feedback from the users.

Once they have undergone formative and summative evaluation, learners are encouraged to review and revise the courseware as necessary, until they have successfully passed the proscribed tests

The transactional nature of the systems approach assumes that the very act of communicating information to the supplicant (sorry, learner) results in the output of "learning."

Adhering to this content development methodology, instructors consider that the channels used to "deliver" knowledge are cognitively neutral and merely replicate and modalities of the classroom - voice-over narration equating to instructor explanation, the screen being equivalent to the overhead projector or blackboard, computer-mediated interaction being the essentially the same as teacher-student interaction, and so on.

By balancing the cognitive load across the learning modalities, it is supposed that knowledge can be effectively delivered, and the student will "learn." A corollory of this is that the learning delivery channels (visual, audial, text-based, and so forth) themselves have no affect upon the learner's interpretation of the content, so to all intents and purposes, the "sage on the stage" transforms into the "guide by the side."
